I'm looking at a 1996 2320 that was repowered with a 2006 Yamaha F250. It looks like its riding low in the aft - the swim platform is at water level. I looked for specs for the boat but cant find what it was originally powered with - the current motor has a weight of a little over 600 lb. Can anyone help me with the specs and whether this is a reason not to proceed? Can you add ballast forward?
